## What it does
**SQL Query Description**
=====================================

### Overview

This SQL query retrieves a list of press brake data from the `PressBrakes` table, filtered by a specific condition related to the `CNC` column. The results are then ordered in descending order by the `PBType` column.

### Breakdown

#### SELECT Clause
-------------------

```markdown
SELECT PressBrakes.PressBrake, 
       PressBrakes.PBType, 
       PressBrakes.CNC, 
       PressBrakes.WC2, 
       PressBrakes.WC3, 
       PressBrakes.WC4
```

This clause specifies the columns to be retrieved from the `PressBrakes` table. The selected columns include:

* `PressBrake`: the press brake data
* `PBType`: the type of press brake
* `CNC`: the CNC information
* `WC2`, `WC3`, and `WC4`: additional values ( likely related to work codes or specifications)

#### WHERE Clause
------------------

```markdown
WHERE (((PressBrakes.CNC)=[Forms]![14" Process Sheet]![txtPrime] Or 
          (PressBrakes.CNC) Is Null Or (PressBrakes.CNC)="ALL"))
```

This clause filters the data based on the value of the `CNC` column. The condition checks for the following:

* If the `CNC` value is equal to a specific string (`[Forms]![14" Process Sheet]![txtPrime]`) or
* If the `CNC` value is Null or
* If the `CNC` value is equal to `"ALL"`

The `[...]` notation suggests that these values are being retrieved from a form or dialog box in an application, possibly related to process sheets.

#### ORDER BY Clause
---------------------

```markdown
ORDER BY PressBrakes.PBType DESC;
```

This clause sorts the results in descending order by the `PBType` column. This means that the press brake types will be listed in reverse alphabetical order (Z-A).

### Example Use Case

This query is likely used to retrieve a list of press brake data for a specific process or project, filtered by the CNC information. The sorted results can help identify the most common or frequently used press brake types.
